Description
SULFONAMIDE COMPOSITION COMPRISING A LIPID-AQUEOUS EMULSION CARRIER Woltfe Harry Feinstone, Indianapolis, Ind.
No Drawing. Application August 12, 1957 Serial No. 677,769
3Claims. (Cl. 167-515) This invention relates to the enhancement of the therapeutic value of drugs administered orally. It has particular, though not exclusive, application to the absorbable sulfonamides. This application is a continuation-in-part of my application Serial No. 442,437, filed July 9, 1954, now abandoned.
It has been common practice heretofore orally to administer absorbable sulfonamides, such, for example, as sulfadiazine, sulfamerazine, su-lfamethazine, mixtures of two or more of these sulfonamides,sulfacetamide, sulfamethylthiadiazole and sulfisoxazole, either as tablets, or as aqueous suspensions.
Feinstone and Williams (Journal of Bacteriology, volume 39, page 47, January '1940) suggested that the absorption of acyl derivatives of sulfanilamide was enhanced by administering them in a suspension of olive oil. However, Climenko, in Patent No. 2,238,973, reported that the absorption of acyl derivatives of sulfanilamide was at most only slightly accelerated by administering them in olive oil. Climenko indicates that in order to produce a therapeutic effect which is appreciably better than that obtainable with the use of a water suspension, an oil to drug ratio of at least twenty to one, and preferably forty to one, must be used with suspensions of sulfonamides in oil. This is shown graphically in Figure 1 of Climenko, in which a two to one oil to drug ratio gave results only slightly better than a water suspension of drug, while a ten to one oil to drug ratio gave results less satisfactory than the water suspension of the drug.
I have discovered that, contrary to the suggestion of Climenko, when absorbable sulfonamides are administered in an emulsion of edible fat and water, as distinguished from unemulsified fat, in which the oil to drug ratio is less than twenty to one and preferably in the range between twelve to one and one to one, not only is the therapeutic activity of the drug enhanced as compared with its activity in aqueous suspension (or in unemulsified oil, of. Climenko, supra), but theabsorption of the drug is markedly facilitated, the blood concentration for the same amount of the drug is almost doubled in human subjects, and an effective blood concentration of the drug is maintained for up to six times as long, as when equal amounts of the drug are administered in aqueous suspension.
These results are set out and discussed in an article in the Journal Lancet, 75: 437 (October 1955), describing the experimental work of Stevens and Henrickson, using triple sulfonamide and sulfadiazine (Lipo-Triazine and Lipo-Diazine, respectively), supplied in the emulsion form of this invention by Donley-Evans and Co.
The following specific examples are illustrative of therapeutic compositions containing absorbable sulfonamides, made in accordance with this invention.
Example I Grams Sulfamethazine 3% Sulfadiazine 3% Sulfamerazine 3 /3 Lipid-aqueous emulsion in sufficient quantity to make The lipid-aqueous emulsion is a standard emulsion-of edible fat and water, and may be made up as follows, the percentages being by weight:
Percent Coconut oil 50.00 Sucrose 10.00 Glyceryl monostearate (stabilizer) 3.00 Polyoxyethylene sorbitan monostearate (nonionic emulsifier) 3.00 Sodium benzoate (preservative) .01 Butylated hydroxyanisole (anti-oxidant) .005 Flavoring materials Ad..lib. Coloring materials Ad.'lib.
Water, q.s. ad., 100%.
The recommended therapeutic dosage schedule is as follows:
Children, initially, 1 teaspoonful per ten lbs. of body weight, followed by one-half the initial dose .every twelve hours;
Adults, initially, .2 to 3, tablespoonfuls, followed by onehalf the .initial dose every twelve hours.
Example 11 5 Grams Sulfadiazine 10 1 Lipid-aqueous emulsion in sufiicient quantity to make As in Example I, the emulsion is standard. It may, for example, have the following composition, in percentages by weight:
Water in sufiicient quantity to make 100%.
The dosage schedule is the same as for the composition of Example I.
Example 111 Grams Sulfisoxazole 20 Lipid-aqueous emulsion in sufiicient quantity to make The lipid-aqueous emulsion is standard, and may be constituted as follows, in percentages by weight:
Percent Cotton seed oil 60.00 Lactose 14.00 Glycerol monostearate 3.00 Polyoxyethylene sorbitan monostearate 3.00 Sodium benzoate 0.02 Butylated hydroxyanisol .005 Flavoring materials Ad. lib. Coloring materials Ad. lib.
Water in sufiicient quantity to make 100%.
The dosage may be as follows:
Children, initial dose, one teaspoonful per each 20 pounds of weight, subsequent dosage, one-half teaspoonful per each 20 pounds of weight every twelve hours;
Adults, initially, two tablespoonfuls, subsequent dosage,
three teaspoonfuls every twelve hours. For severe infections, the same dosages may be given every six to eight hours.
Any of the variuos absorbable sulfonamides or acetylated sulfonamides may be substituted for the sulfonamides set forth in the foregoing examples. The non-absorbable sulfonamides, such as sulfaguanadine, phtha1yl--- sulfacetamide, phthalylsulfathiazole and succinylsulfathiazole, which are employed chiefly for their anti-bacterial action against organisms inhabiting the intestinal canal, are notsuitabletoadministration in oral lipid emulsions, since their absorpiotn into the. blood stream is not def 'sirable. H 7 As has'been pointed out in the examples themselves, the oil-water emulsion is a standard one, prepared by the usual procedures, such as those'set out in the U. S. Dispensatory. It is, however, absolutelyessential that the lipid constituent be what is commonly designated edible, digestible-or absorbable fat, derived from animal or yegetable sources. Examples of such fats,'in addition to the ones-set-outin-the examples above, include peanut oil,
. butter fat, pecan-oil, beef'fat, lard and mutton fat. This list is merely illustrative. The fat-should constitute 20% to 60% of the emulsion, by weight. w
' Whil'e'the ratio'of oil to drug in the examples, given, ranges from approximately five to one to approximately three to one, the preferred range extends 'from'about twelve to one to about one to one, this being the present normal dosage range. Thus sulfadiazine', sulfamerazine and sulfamethazine, either singly or in combination, are normally prepared in dosages of 0.5 gram per 5.0 cc. of suspension; sulfisoxazoleis presently being prepared in dosages of 1.0 gram per 5.0 cc. of suspension, and sulfamethylthiadiazole ispreesntly being prepared in dosages of 0,25 gram per 5.0 cc,
- "2."A therapeutic composition for oral administration comprising sulfadiazineand a lipid-aqueous emulsion containing 20% to 60% by weight 'of an edible fat, the concentration of the sulfadiazine being 0.5 gram per 5 cc. of said composition.
3. A therapeutic compositionfor oral administration comprising absorbable sulfonamide and :a lipid-aqueous emulsion containing 20% to 60% by weight of an edible fat, the oil to drug ratio of the composition being between about one to one andabout twelve to one. I 1
